单项选择题
In information technology there seems to be a revolution every other week. At least that is the impression one gets when following media coverage of the sector. Yet sometimes the hype (夸大的宣传) is justified, in particular in the case of open-source software, free programs developed by loosely knit groups of developers. Within just 15 years they have completely changed the (62) of the software industry, turning it from a mostly capitalist economy into a mixed one.
The shift should be (63) interest--and not just to techies. Software is important stuff; it keeps the world moving. No car, no television set, not (64) a modern toaster works without some code. Take corporate computer programs away, and the economy comes to a grinding (65) . In some cases software has changed (66) humans behave； spreadsheet programs, for instance, have (67) more than one job.

Developers contribute (72) , and share code freely.
Open source is actually nothing new. Sharing of source code was (73) in the early days of computing, when software was not (74) as having market value and most developers were academics. But companies soon discovered that selling proprietary(专利的) software can be a very (75) business. To recreate a software commons, a group of politically motivated programmers came up (76) a special usage licence in the early 1980s to protect "free software", (77) it was then called.
This approach, known as " copyleft", as opposed to copyright, faded in (78) until the Internet made it easier for remote groups of developers to (79) --which led to an explosion of open-source activity. Today SourceForge, an online home for such projects, hosts thousands of them. More importantly, open-source software has become an (80) part of information technology. In some markets, for instance, Linux is more successful than Windows. And Android, the fastest growing operating system for smart-phones, is (81) open source.
